Dear patient thank you for your question. To start off it is illegal for any one to inject hydrocortisone injection if he does not at least have an m.b.b.s degree. Either the injection has been put at the wrong place or it has penetrated a nerve leading to injection related neuropraxia. In that case ibuprofen 800mg twice a day with pantoprazole once a day will help. This is a self limiting condition and will take at least 4 weeks for the pain to decrease. on the X-ray my calival is coming up through top of my shoulder . This is what you have mentioned in the question and o think you meant to say clavicle. UNfortunately unless i see the xray i cannot make a diagnosis as it would be ethically wrong. I suggest you show it to an orthopedic surgeon. I hope this helped
